To all wlwgnit may concern:

Be it known that I, Emma E. HAUER, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Strainers, of which the following is a specification, reference being had therein to the accompany: ing drawings.

be introduced into a pipe line to remove foreign matter from the fluid passing through the line.

The object of my invention isto provide an improved strainer, simple and elfective in operation, in which both movable and stationary strainer elements are employed combinations hereinafterdescribed and set forth in the claims.

In the drawings Figure 1 is a vertical section on the line 11 of Fig. 2 of a strainer embodying my invention, and Fig. 2 is a like section taken on the line 2-2 of Fig. 1.

Like numerals represent the same .parts in the two views.

In the drawings 1 represents a casing with heads 2 and 3 bolted thereto forming a straining chamber 4 having an inlet 5 and an outlet 6 with suitable flanges as shown to connect the same in a pipe line. Said casing has an extension 7 which may be secured thereto in-any suitable manner a by bolts as shown. This extension provides a settling chamber 8 and a cleaning or discharge chamber 9 arranged below the straining chamber and having an opening 10 for a valve as shown.

A stationary cleaner element which is shown in the form of a perforated diaphragm 11 is fixed in the outlet 6 of the straining chamber; and a movable strainer element is also provided which is shown in invention relates to strainers and more particularly to a strainer adapted to the form of wheels arranged at. o posite ends of the'straining-chamber and aving hubs 12 with spokes 12 and rims -12 to which perforated .WBbS 13 are riveted as shown or secured in any suitable way. A

has its reduced ends journaled in the opposite heads of the casing and extends through one of the heads and 1s provided with a stufling box 15 to prevent leakage. Abandwheel '16 fixed to the shaft is provided with a stop 17 which normally engages a recess in the hand-wheel by pressure of a\spring 18; but can be moved and held out of engagement by a'handle 19'fixed to the-stop,

19 through which the handle moves and a set-ofl' or recess 19 into which the handle is turned to hold the stop out of engagement with the hand-wheel.

the stop-holder having a longitudinal'slot A hollow plug valve 20havinglongitudinally extending ports 21 is seated inthe opening 10 between the settling and cleaning or discharge chambers and is tightened and held in place by a nut 22 and a'lock-nut 23; and a handle 24 fixed to one end'of the valve is provided to operate the same.

A head 25 swings upon a hinge 26 secured to the casing extension and is normally held closed by bolts 27. Said head is provided with an annular groove or recess in which a packing 28 is secured to insure a tight joint when said head is closed.

It will be seen that the inlet --5 and outlet 6 are in line with eachlother and with the upper half of the wheels and that by reason a of this arrangement the flow of the fluid passing through will cause the wheels to rotate and the refuse caught by the webs will be carried by them and dropped into the chamber, the valve 20 is closed and the head 25 is released and swings on its hinge to open position.

When the strainer is employed in a suction line and the valve is closed ahd the" cleaning' chamber open for cleaning, it is essential that no air be admitted to the line, and to prevent leakage through the valve a water-seal is provided, water being introsettling and discharge chambers. The Sta-' Toremove the refuse'from the cleaning" 60 shaft 14 upon which the wheels are fixeda movable strainer element, one of said duced to the valve for this purpose through the pipe 29 connected to any suit'ablesouree of supply. I

That portion of the straining chamber that is occupied by the lower half of the wheels may also be regarded as a settling chamber, but the settling chamber 8 proper is beyond .the movement of the webs and will receive the refuse whether the valve is closed or not.. v a

It will be further noted that means are provided to move the movable strainerv elementa'nd to hold the same stationaryat the will? i the operator.

H thus described my invention I rainer, a casing, a stationary and strainer elemen eration being," to cleanrthe othe 2.111s trainer, acasing, a stationary and a movable. strainer; element, said movable strainer element bein contact with and" ada ted to] clean f tionary strainer. e ement by the flow of; the bea normal straining opontaet with and adapted ing transmitted,

-3. In astrainer, a casing,a stationary and;

a movable strainer element, one, oii said' strainer elements its normalstraining operation being incontact with and adapted to clean the other and means to hold and move said movable strainer elementat will.

4. In a strainer, a casing, a stationary and a movable stramer element, said mov able strainer element being in contact with and adapted to clean said stationary by the flow of the fluid being transmitted.

6. In a strainer, a casing, a strainer element and means in contact with and adapted to clean said strainer element, said means arranged to act as a strainer and adapted to be operated by the flow of the fluid being transmitted.

7. In a strainer, a casing having a straining and a cleaning chamber, a strainer element and means arranged to act as a strainer and operated by the flow of the fluid being transmitted, to clean said strainer element and carry the refuse from said straining chamber to said cleaning chamber, said means being in contactwith said strainer element;

8. Ina strainer, a casing having a strainstationary and a movable strainer element,

said movable strainer element being in contact with and adapted to clean said stationary strainer element by the flow of they fluid being transmitted and means between said straining and cleaning chambers to prevent the escape of the fluid when said normally closed outlet is open. a

10. In a strainer, a casing having acylindrical straining chamber, with an inlet and outlet in the upper portion thereof adapted to be connected in a pipe line, a stationary strainer element at said outlet and a rotary strainer element-in said straing chamber in contactwith said stationary strainerelement. I r 11. In a strainer, a casing having a cyv lindricalstraining chamber and a cleaning 95 chamber having a normally closed outlet, "saidf cylindrical straining 4 chamber having an inlet and outlet in the upper portion thereof adapted to be connected in a pipe line, a stationary strainer element at said outlet, a'f'rotary strainer element in said I straining chamber operated by the flow of the fluid and in contact with and adapted to clean said stationary strainer element and means between said straining and cleanin chambers to preven't'the escape of the flui when said normally closed outlet is open.

12; In a strainer, a casing having a cy-' lindric'al straining chamber, a settling chamber underneath and open to said straining chamber anda cleaning chamber below said settling chamber with an opening therefrom, a wheel mounted in said straining chamber and having radially disposed fgerforated webs, said straining chamber aving an inlet and outlet adapted to be connected in a pipeline and arranged in line witheach other and with the upper half of said wheel, a stationary perforated diaphragm at said outlet with which said wheel contacts, said cleaning chamber havin a normally closed outlet and a valve to c ose theopening between said settling and cleaning chambers when said normally closed outlet is open. 1

13. In a strainer, a casing having a straining chamber with an inlet and outlet and a cleaning chamber with a normally closed outlet, a strainer element, means in contact with and adapted to clean said strainer ele- 1 ment and carry the refuse to said cleaning chamber, a valve between said straining and cleaning chambers, a Water seal for sziid Valve to prevent the admission of air when said normally closed outlet is open and the strainer is employed in a suction line.

In testimony whereof I have hereunto aflixed my signature in the presence of tWo witnesses.
